The wife and I bought a second home in Lake Arrowhead CA in October of last year. We then decided this is going to be our retirement home (we retired in January.). It has 1400 sq ft of unfinished build up area under the main/ground floor. This thread will be the ongoing story of my building of a 250 sq ft studio in the build out area.

The first pic is what the area looked like when we bought the place. Pretty rough. So we started the floor construction this week and finished today! I ran three 3” ABS pipes under the floor to fish cables through from one side to the other. The pipes coming out of the floor are not yet cut to the correct height. The floor is insulated with R38.

The room will be powered with two 20 Amp circuits and one 15 Amp circuit. The 2 exterior 2x6 walls resting on the concrete foundation will have an air gapped 2x3 wall on the interior and then filled with R30 insulation. All the walls will have double sheeted 5/8” dry wall with acoustic caulk/glue in the joint and between layers.

More to follow…

Coming along nicely

It's a bummer that air duct runs the way it does. You could chang it to square duct. 4"x10" square duct would get you a little more head room, then be sheetrock around to look like a beam. I've been doing heating and air for about 20 years.

LRT, I'm going to use 3 1/4 x 10 galvanized steel duct work to get it cleaned up against the ceiling. The ceiling will have a noise mat layer and then a resiliency channel air gap layer with two 5/8" sheetrock layers hung on that. The duct work will be molded into that.

Nice
Sounds like you are going to do what I'd like to do in my room. I've looked into acoustic insulation to reinsulate with and then the acoustic mat. My space isn't part of my house and I live in the country so it's not big priority right now. But I do want to hold the sound from getting to the house. My family says the cant hardly hear us anyhow.

Heres a link to what I've looked at

That looks like the stuff I was looking. Not cheap and very heavy, lots of mass.

Does this stuff go anywhere there is sheetrock? How about the floor?

There is no reason it couldn't go you couldn't put it under the floor. I dont think I'd put it onto of the floor though. If you put it under the floor joist it would act as a vapor barrier like a belly liner in a Mobil home. If it's for a second level floor I'd maybe think of using rubber mat, it's not cheap but there is different thicknesses. Most feed stores will have it, I have seen 3/4 thick around here.
